The Japanese person (or people) behind the website www.gamedesign.jp are mysterious to me. I know nothing about them, except that they’ve been making games, first in Flash, then more recently using the Ruffle runtime, since at least 2001.
While the title under which they put up their efforts may not be memorable, if you’ve been playing web games for a while you probably know some of their work. Possibly their best-known game is DICEWARS, which is like a version of Risk that plays much much faster, most games over in minutes, instead, as with the people I know who have played it, of days.
In DICEWARS (several of GAMEDESIGN’s games are stylized with allcaps), you have nation whose territories are represented as colored areas, each containing a stack of from one to eight six-sided dice. Each nation gets a turn to act, during which they can use a stack of dice to attack the dice of a neighboring country. Fights are resolved by rolling all of the dice in the two stacks. If the attacker wins, they move all of their stack save one into their conquest and take over (the enemy dice are lost), with that single die remaining in the stack’s previous home to keep the lights on.
If the defender rolls higher, or there’s a tie, the attacker loses all of their dice in the stack except one and the defender loses nothing. A stack of one can’t attack, and is generally pretty easy to slaughter by other nations; a good element of strategy is figuring out how to keep high-dice stacks near the front, between enemies and your single-die lands, since you can’t manually move dice around between your territories. When a nation is done acting for a turn, they receive extra bonus dice relative, I think, to the largest contiguous group of regions they control. They are placed randomly among all their possessions.
Various versions of DICEWARS can be found on mobile app stores, although I don’t think any of them are officially blessed, and they tend to disappear after awhile.
It turns out they have a lot of other games that you may know of. One of particular note is Fairune, which is a capsule, very much simplified JRPG. Fairune and sequels made it to the 3DS and Switch eShops, where they are very inexpensive and enjoyable. Fairune is copyrighted by SKIPMORE, which may be a different entity. It’s still a nice game, worth looking into.
EDIT: SKIPMORE has their own website, which now mostly presents their downloadable console and mobile games.
